E3FS

Precautions

Indicates a potentially hazardous situation which, if not avo-

ided, could result in death or serious injury. Indicates prohibi-

ted actions.

When the E3FS is used without a safety control unit, do not

use the E3FS as a safety device nor a part of safety systems

for ensuring safety of persons.

When the E3FS is used without a safety control unit like the

F3SP-U1P-TGR, it is in accordance with the requirements of

the safety related control system to category B as defined in

the European standard EN954-1.

The E3FS is in accordance with the requirements of the safety

related control system to category 2 only when it is connected

with a specified control unit.

E3FS-10B (PNP):

Type F3SP-U1P-TGR safety control unit must be used.

The F3SP-U1P-TGR executes a periodic test every 27 ms.

Make

sure

that

personnel

operating

the

E3FS

are

knowledgeable about the machine on which it is installed.

Read this manual and the control unit manual completely.

Be sure the information provided is understood before

attempting to operate the E3FS.

Multiple E3FSs must be sufficiently far from each other to

avoid mutual interference.

Regarding the calculation of the safety distance, obey the

control unit manual and related standards, e.g. EN999 when

the E3FS is used as a safety device.

Regarding the avoidance of malfunction caused by shiny

surface, obey the control unit manual when the E3FS is used

as a safety device.

Use an opaque test piece with 11 mm in diameter and 200

mm or greater in effective length to check the detection

capability.

Do not connect the E3FS to an AC or DC power supply with

higher voltage than nominal 24 VDC. Otherwise the sensor

may explode, burn, or cause electric shock.

The power supply must conform to regulatory requirements

and standards, regarding EMC and electrical equipment

safety, of the country where the E3FS is installed. For

example, the power supply must fulfil EN60742 requirements

for double insulation and must conform to EMC Directive and

Low Voltage Directive in EU.

A load must not be shorted.

A load must not be used with current higher than the rating.

Do not apply the reversed supplied voltage.

Be sure to route the E3FS cable separated from high-

potential power line or through an exclusive conduit.

E3FS must not be used in water.

The E3FS is ready to operate 100ms after the E3FS is turned

ON. If the load and E3FS are connected to independent

power supplies respectively, be sure to turn ON the sensor

before turning the load ON.

do not extend it more than 50m.

Do not use the E3FS in explosive or flammable gas.

Do not disassemble, repair, and modify the E3FS.

Do not exceed a torque of 2.0N·m (20Kgf·cm) when tightening

mounting nuts for plastic models

20.0N·m (200Kgf·cm) when tightening mounting nuts for

metal models.

For connector type of E3FS, make sure the cable connector

is rated IP54 or higher.

Be sure to connect or disconnect the connector after turning

OFF the E3FS.

Hold the connector cover to connect or disconnect the

connector.

Secure the connector cover by hand. Do not use any pliers.

The proper tightening torque range should be checked

according to connector specification. Be sure to tighten the

connector securely.
